Fairy Godmother

In fairy tales a fairy godmother
is a fairy with magical powers who acts as a mentor or parent to
someone.
The fairy godmother is a character in stories that tests the
hero/heroine (and sometimes other characters as well) and provides
magical assistances to the hero/heroine while he/she succeeds.
Fairy
godmothers appear frequently in stories especially re-telling’s of Cinderella and Sleeping Beauty

Mercedes Lackeypresents
a gently lampooned version of the concept in her Tales of the Five
Hundred Kingdoms series, in which the Fairy Godmother role is a career
option for young women when the “Tradition” has tried to force them on
a story that does not work out probably.
This means these women have an
excess of magic, if they can access this magic and receive the blessing
of the Fae folk, they are granted the gifts of being a Fairy Godmother.

In Sherk 2 the Fairy Godmother
turns out to be a conniving, crooked businesswoman, who is quite
willing to resort to blackmail and murder to further her own interests.
The pure reason for helping princesses gain a happily ever after with
Prince Charming, is that Prince Charming is actually the Fairy
Godmother’s son, and through the marriage he will gain the throne!
